Demonstration of the superior ophthalmic vein by high resolution computed tomography.

Computed tomography has revolutionized the diagnosis of ophthalmologic and neuro-ophthalmologic disease. High resolution CT with thin-section techniques has made available the depiction of finer anatomic orbital detail and permits radiologic detection of more subtle lesions than was previously available. The display of normal-sized superior ophthalmic veins by CT is further evidence of the resolving power of the currently available machines. A segment of the superior ophthalmic vein was identified in 18 of 64 orbits examined by CT. Virtually the entire superior ophthalmic vein was identified in three orbits.
